CANDY-PULLING MACHINE.

Specification of Letters Patent.

Patented Mar. 23, 1915.

Application filed February 16, 1911. Serial No. 608,953.

To all whom it may concern Be it known that We, MAXIMILIAN E. BUHSE, VVALTER W. BUHsE, ALEXANDER F. BUHSE, and HENRY L. BUHSE, citizens of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Candy-Pulling Machines; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and usethe same.

Our invention relates to candy pulling machines and has for its special object the provision of a highly efficient machine of this character. To the above ends the invention consists of the novel devices and combinations of devices hereinafter described and defined in the claims.

In the accompanying drawings, which illustrate the invention, like characters indicate like partsthroughout the several views.

Referring to the drawings: Figure 1 is a plan view of the improved machine, some parts being broken away and some parts being sectioned; Fig. 2 is a side elevation of the machine, with some parts broken away and with some parts sectioned; Fig. 8 is a transverse vertical section taken approximately on the line 00 m of Fig. 2, some parts being broken away; Fig. 4 is a fragmentary view in longitudinal section taken approximately on the irregular line 00* m of Fig. 3; and Figs. 5 to 11 inclusive are diagrammatic views illustrating the different pulling movements produced in the candy during" the pulling action.

The machine illustrated in the drawings is a double machine adapted to pull two batches or hanks of candy at one time, whether of the same or of different flavors, but it will of course be understood that the same principles of construction may be incorporated in a single machine.

The body 1 of the machine frame is, as shown, a regular cast box-like structure supported by legs-2, and the said legs at each side of the machine preferably support wood working-tables 3.

The pulling device at each side of the machine comprises a relatively fixed pulling pin 4 and apair of movable pulling pins 5.

The fixed pulling pins 4 are rigidly secured to the forwardly extended ends of a cross bar 6 that is rigidly secured'to what may be treated as the front end of the frame 1. The movable pins 5 are rigidly secured to the ends of crank bars or heads 7 rigidly secured at their intermediate portions to a transversely extended shaft 8. This shaft 8 is mounted to rotate in bearings 9 of a traveling carriage 10, which latter is mounted for horizontal sliding movements longitudinally of the machine in elongated runways 11 formed in the upper side portions of the frame body 1. The shaft 8 is preferably arranged with its axis in a horizontal plane of the fixed pulling pins 4, and the crank heads 7 carried by the ends thereof are ranged inward of the inner ends of the said pins 4 so that the said shaft 8 may be moved into axial alinement with the said pins 4.

Rigidly secured to the bottom of the carriage 10 is a pair of rack bars 12 having frame body 1. These pinions 13 are journaled to a cross head 15. that is supported by and has threaded engagement with a long centrally and longitudinally of the frame body 1 and is ournaled in suitable bearings 171819 on tlieend portions of said frame body, and is held against endwise movements by the said bearings. At the rear end. of the machine the screw shaft 16 is provided with an intermediate pulley 20 that is fixed thereto, and at the front and rear thereof with loose pulleys 21 and 22. Two belts not shown will be arranged to normally run one over each of the loose pulleys 21 and 22 and these belts will run through the looped arms 23 of a belt shifter compris ing also a pivoted cam acting shipper head 24 supported by frame body 1. This belt shifter is of the ordinary type used in connection with planers, and for the purposes screw shaft 16. The screw shaft 16 extends other belt will be moved onto the said pulley 20. In this way reverse rotative movements may be imparted to the screw shaft 16.

The belt shifter above described is operated by the traveling carriage 10 and as shown this is accomplished through a long shipper bar 25 that is mounted to slide endwise through bearings 26 on one side of the frame body 1. The carriage 10 is provided with a shipper lug 27 having a perforation through which the bar 25 works loosely. For cooperation with the shipper lug 27 the bar 25 is provided on each side thereof with collars 28 adjustably secured on the said bar 25 by set screws 29.

The adjustment of the collars 28 on the bar 25 determines the extreme traveling movements of the carriage 10. The front collar 28 should be so adjusted that the shaft 8 will be in approximate alinement with the fixed pulling pins 1 at the extreme forward movement of the carriage. The rear collar 28 will be set in different positions on the bar 25 according to the amount of movement that it is desired to give to the carriage 10.

Loosely journaled on the intermediate portion of the crank carrying shaft 8 is a spur gear 30 that meshes with a rack bar 31 secured to the top plate of the frame body 1. The gear 30 carries one or more spring pressed pawls 32 that engage with a ratchet toothed hub 33, rigidly secured to the shaft 8 adjacent to the said wheel. This pawl and ratchet device 3233 will cause the crank shaft 8 and its crank 7 to rotate when the carriage 10 is moved forward or toward the fixed pulling pins 4, but permit the said shaft and its cranks to be held against rotation when the said carriage 10 is given its reverse or return movement toward the rear of the machine.

As is evident when the screw shaft 16 is rotated, it will move the cross head 15 in the one direction or the other, according to the direction of rotation. of said shaft, and through the pinions 13 carried by the said cross head, the carriage 10 will be moved in the same direction as the cross head, but at twice the rate of speed. As otherwise stated, the carriage will move always in the same direction as the cross head, but will be given twice as much movement as the cross head in a direction longitudinally of the machine.

In the diagrammatic views Figs. 5 to 11 inclusive the bank or drawnout soft bar of candy is indicated diagrammatically by the character z The hank of candy is first applied to the pulling pins 4- and 5 substan tially as shown in Fig. 5, either while the said pins are separated as shown or while they are moved closer together. At any rate, when the carriage 10 first reaches its extreme rearmost position after the candy has been applied to the pulling pins the hank will be drawn out approximately as shown in Fig. 5. Then when the carriage begins its forward movement the cranks 7, which carry the pins 5 will commence to rotate and will continue their rotary movement throughout the forward movement of j the carriage and until the crank shaft 8 is moved forward approximately into aline ment with the fixed pins 4. Figs. 6, 7, 8 and 9 illustrate progressively the operation of the revolving pins 5 during the forward movement of the carriage, and Fig. 10 shows the relative positions of the three pulling pins at a time when the carriage has reached its extreme forward movement and is just ready to begin its return movement.

Fig. 11 illustrates the drawing action on the hank when the carriage is given its return movement while the cranks and the pins 5 remain stationary in respect to the said moving carriage 10. When the carriage is again moved forward the revolving movements of the pins 5 will again be repeated and the hank will be again wound up. This combined winding and pulling action insures thorough mixing of the candy, thorough aerating thereof, and generally stated a very high grade of work.

The means for varying the length of stroke or traveling movement of the carriage of the machine is of very great importance, because it adapts the machine to handle candy of various degrees of hardness. Hard candies will not stand being pulled out to as great length as the softer candies and furthermore the length to which the candy hank should be pulled will also depend somewhat on the size thereof. This machine is universally adaptable to all of these conditions and the amount of rotary movement given to the cranks will always be proportionate to the length of travel of the carriage and will be suflicient in all cases to wind up the stretched hank when the carriage is moved toward the relatively fixed or local pulling pin. The expression, local pulling pin does not necessarily mean that the said pin has no movement whatever, but it .means that the pin occupies a certain position in respect to the pins carried by the traveling carriage and the cranks thereof, so that in one position of the carriage the pins on the rotating crank may travel around said local pin.

As already indicated, with the double machine candies of different flavors may simultaneously or successively be pulled on the machinewithout requiring the cleaning of previously used pulling pins or pegs. The term pulling pins is used in a broad sense to include any kind of projections that are adapted to directly engage with the candy hank in the pulling action.
